The Prevalence and Associated Factors of Hypertension among Adults in Southern Ethiopia

Background. Hypertension is a growing public health problem in many developing countries including Ethiopia. Determining the prevalence of hypertension and identifying the associated factors is crucial. Objective. To assess the prevalence of hypertension and associated factors, among adult population of Arba Minch town, Gamo Zone, Southern Nations, Nationalities and Peoples Region, Ethiopia. Methods. A cross-sectional study design was conducted from December 1 to 30, 2017 among adults. Study participants were selected using a multistage systematic sampling method. Data were collected by face-to-face interview after getting written informed consent by using a structured questionnaire. Additionally, weight, height, and blood pressure of participants were measured following standard procedures. Data were entered into a computer using EPI INFO 7 and exported into SPSS version 20 for analysis. Bivariate and multivariable analyses were performed to explore the association between hypertension and associated factors. Multivariable logistic regressions were fitted to control the effect of confounders. Results. A total of 784 study participants were included in this study. The overall prevalence of hypertension in Arba Minch Town was 35.2%, (95% CI: 32.4%, 38.4%). Nearly 90% of hypertensive patients were screened for the first time. Age ≥55 years [AOR=7.74; 95% CI: 2.19, 27.23], income level which is greater than 2501 Ethiopian Birr [AOR=9.5; 95% CI: 4.5, 20.20], working hour less than seven hours per day [AOR=12.5; 95% CI: 4.3, 36.1], and chewing “khat” [AOR=11.06: 95% CI: 4.3, 27.7] were the independently associated factors with hypertension. Conclusion. The prevalence of hypertension is found to be high. Increasing awareness on control use of “khat,” increasing physical activity, and strengthening community-based periodic screening programs of high-risk populations are recommended
